Sounds pretty typical of a dog that has been having a lot of stress in it's life. A change of home can be really hard on some dogs, especially with softer temperaments. Sounds also like she might be used to bonding with only one person, then getting her way with that situation. Than is why she gets upset with you out of sight. She is trying to find some normalcy by bonding wth you and then controling you right off the bat.
She needs you to let others take care of her for the majority of her daily needs, walks, food, water and training. You also need to nip her anxious behavior in the bud, tell her NO firmly and walk away then ignore the rest. Ignore her until she stops fussing. No eye contact or talking to her until she is quiet. This will work but it may take some time.
